cpufreq-aperf
Cpufreq-aperf is a command-line tool used to monitor the frequency and performance states of the CPU. It allows users to get insights into the behavior and utilization of their CPU in real-time.
One of the main features of cpufreq-aperf is that it provides detailed information about the CPU frequency, current performance state, and utilization. This enables users to analyze and optimize the performance of their system.
The tool supports various CPU architectures and can be used on both Intel and AMD processors. It operates by reading the counters provided by the ACPI (Advanced Configuration and Power Interface) framework.
Cpufreq-aperf can be used to measure the impact of different workloads on CPU performance and power consumption. It is particularly useful for system administrators, developers, and power users who need to understand and optimize their systems' CPU behavior.
The tool provides multiple modes of operation, including real-time monitoring, logging, and benchmarking. It offers various parameters to customize the monitoring and logging behavior, such as sampling interval, duration, and output format.
Cpufreq-aperf also supports exporting data to other formats, such as CSV or JSON, which allows users to further analyze the collected data using external tools or scripts.
The tool is open-source and actively maintained, which means that users can contribute, report issues, or suggest improvements to the project.
Cpufreq-aperf is a command-line tool, which means it can be easily integrated into existing scripts or used in conjunction with other command-line utilities for more advanced monitoring and analysis.
Overall, cpufreq-aperf is a powerful and flexible tool for monitoring and analyzing CPU performance and frequency states, providing users with valuable insights to optimize their system's performance and power consumption.
